Skepticism is a primary tool of science. It would be hypocritical to never direct skepticism towards scientific skepticism itself. If the existence of our own imperfections and errors is denied, then they are free to grow without limit, and skepticism is not immune to this problem. Unbridled gullibility can destroy science, but unbridled skepticism is no less a threat because it brings both the excessive preservation of the status quo and the supression of unconventional ideas. Better to take middle road between total close-mindedness and total gullibility. Practice pragnatism, pursue humility, and maintain a clear, honest, and continuing view of ourselves and the less noble of our own behaviors.

(vrij vertaald uit bovenstaande engelse text)

"The scientists from Franklin to Morse were clear thinkers and did not produce erroneous theories. The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane."
"Today's scientists have substituted mathematics for experiments and they wander off through equation after equation and eventually build a structure which has no relation to reality."
